  • Patent number: 6857485
    Abstract: A water-base drilling fluid for use in drilling wells through a formation containing a shale which swells in the presence of water. The drilling fluid preferably includes: an aqueous based continuous phase, a weight material, and a shale hydration inhibition agent having the formula: H2N—R—{OR?}x—Y.[H+B?]d in which R and R? are alkylene groups having 1 to 6 carbon atom and x is a value from about 1 to about 25. The Y group should be an amine or alkoxy group, preferably a primary amine or a methoxy group. The acid H+B? is a protic acid selected from the group consisting of inorganic acids and organic acids, illustrative examples of which include: hydrochloric, hydrobromic, sulfuric, phosphoric, nitric, boric, perchloric, formic, acetic, halogenated acetic, propionic, butyric, maleic, fumeric, glycolic, lactic, citric and combinations of these. The shale hydration inhibition agent should be present in sufficient concentration to reduce the swelling of the shale.

  • Patent number: 6858309
    Abstract: The present invention provides improved methods for conducting living/controlled polymerization on polymeric solid supports. The improved methods allow polymerization to occur directly from the non-functionalized surface of a bulk support. In addition, polymerization may be re-initiated to provide co-polymers. The disclosed methods may employ the non-nitroxide-based RAFT and ATRP control agents that allow controlled polymerization to proceed at relatively low temperatures (<80° C.). Furthermore, these improved methods may provide graft polymers with decreased levels of “in-growth” of the bulk solid support. The invention also provides substrate polymers, with improved properties for solid phase synthesis and diagnostic applications, which may be made by the disclosed methods.

  • Patent number: 6854960
    Abstract: In the embodiments described in the specification, an impeller is manufactured by providing a mold for one angular segment containing one vane of an impeller and corresponding hub and rim portions, injection-molding fiber-reinforced polymer composite resin material into the mold to produce a plurality of substantially identical segments, and assembling the segments into an impeller by bonding corresponding mating end surfaces of the hub and rim portions of the segments. A veil cloth is applied to the outer surface of the rim portion and impregnated with resin material to complete the impeller structure.

  • Patent number: 6855840
    Abstract: Polymers and copolymers synthesized by means that yield a narrow range of molecular weights can have different properties than polymers synthesized by conventional means. In order to obtain such polymers, however, polymerization must be controlled. One type of controlled polymerization is the reversible addition-fragmentation chain transfer (RAFT) process, which has characteristics of a living polymerization. The present invention discloses a group of dithioesters and trithioesters suitable as chain transfer agents for RAFT polymerization. The present invention also discloses RAFT polymerizations conducted in aqueous media.

  • Patent number: 6856656
    Abstract: An iterative system for performing carrier phase tracking of symbols using a serial turbo decoder. Estimates of a buffered block of symbols are provided by a serial turbo decoder. Optionally, reliability metrics for the estimates are provided as well. Responsive to this information, a tracking loop module determines derotation phases for each of the symbols in the buffer. A symbol derotator derotates each of the buffered symbols in the block by its corresponding derotation phase. The derotated symbols are stored back in the buffer. The process may repeat itself for a prescribed number of iterations, after which the serial turbo decoder provides estimates of the underlying source bits.

  • Patent number: 6851279
    Abstract: Jewelry articles having magnetic elements and interchangeable settings are disclosed. In one aspect, the jewelry articles include magnetically coupling body portions and interchangeable settings. The body portions magnetically couple together to hold the interchangeable settings. For example, the body portions can magnetically couple together using rare earth magnets to form a composite ring. Preferably, at least one of the body portions is rotatable to tangentially break the magnetic coupling between the body portions to interchange the setting. In another aspect of the present invention, magnetic elements are used to magnetically suspend a movable setting on a jewelry article. An longitudinal member has at least one end connected to the jewelry article. The setting is movably disposed on the longitudinal member. A first magnetic element adjacent an end of the longitudinal member magnetically repels a second magnetic element on the setting.

  • Patent number: 6847938
    Abstract: A method and system is taught for coordinating the exchange of goods between parties over a communications network such as the internet. Users of the system can interact with a central computer to input data regarding items that they offer for exchange, as well as search criteria describing items that they would like to receive in exchange. A processor in the central computer searches records stored in a database to find and sort those records that satisfy the user's search criteria. A second test is then be performed to determine whether the information that the user input describing the item offered for exchange satisfies search criteria within the record. As a result, a match may be generated between two users who have input complementary criteria. The invention can also accommodate more complex exchanges between three or more parties.

  • Patent number: 6847145
    Abstract: Encapsulation of a permanent magnet rotor is achieved by applying a glass roving material to spaces in the rotor structure, applying a veil cloth around the outer surface of the rotor, mounting a vacuum bag with vacuum ports around the outer surface of the rotor, removing vent plugs from the end walls of the rotor and screws from an inner ring of the rotor and replacing them with vacuum ports and applying a vacuum to the vacuum ports. After air has been removed from the rotor, an encapsulating resin is applied to some of the ports to introduce resin into the interior of the rotor. After curing of the resin the vacuum bag is removed and the outer surface of the rotor is machined to the desired outer dimension of the rotor.
